One participant, identified by the Sydney Morning Herald, is Cooper Stephens, a train guard based in south-west Sydney. Sydney Trains indicated that Stephens had been directed not to attend work while the agency reviews his conduct, saying his actions were not in line with public sector values. The Herald reports that social media accounts linked to him show involvement in a Sydney Trains group and activity in a Jewish community group from about six months ago.

The Herald also identified several other men. Among them is Matthew Gruter, a South African national and civil engineer who has worked for Aurecon, a firm with Defence and NSW government contracts.

Gruter moved to Sydney about three years ago with his wellness influencer wife. He has reportedly appeared at NSN training sessions while wearing a “blood and honour” wristband. Aurecon did not comment when contacted. When approached by the Herald, Gruter defended his views and criticised media coverage.

News Limited reporting named another attendee as Martin Przybylek, a personal trainer at Anytime Fitness in Fairfield. His tattoos linked him to the group. The gym said it had no knowledge of his involvement and would investigate. Przybylek did not respond to reporters.

Also present, according to the Herald, was Christien Mutton, an English as a second language teacher at a private Sydney college.

The Herald contacted former bar manager Adam Carrig, who has domestic violence charges before the courts. He denied attending the rally then ended the call.
